A lot of us often refer to it as Laguna Seca, but over the last 17 years, the Monterey, California-based racetrack was officially called "Mazda Raceway Laguna Seca." The name was part of a naming rights sponsorship the track had with Mazda. If you’re not used to calling it by its official name, don’t start now because the Japanese automaker has decided to end its naming rights agreement with the facility. The partnership expires on March 31, 2018, and unless Mazda has a change of heart, the track will go back to being officially known as Laguna Seca.
